Shadowmourne

Lore

As the Alliance and Horde forces as part of the Ashen Verdict were built up to face the Lich King inside Icecrown Citadel, many of them realised that they were no match for the power of Frostmourne. However, Darion Mograine was aware of the power another weapon born of sacred and corrupt powers, Shadowmourne, that had yet to be crafted but would be key to matching the power of Frostmourne and defeating the Scourge forces. 
 
The axe was to be treated by only master metal-shapers and crafted with many piles of Saronite, it needed to be drenched in the souls of the Lich King's most powerful servants to fuel it's power to kill and it was to be host to thousands of dead souls. To break through the Lich King's armor the axe was to be graced with fifty fragments of the Frozen Throne. With all these makings it would allow the Ashen Verdict to stand any chance of defeating the Lich King and his forces.
